A 63-year-old female was presented to emergency room with an abdominal pain. The patient had moderate mitral valve stenosis and atrial fibrillation. Abdominal computed tomography revealed right renal infarction. Transthoracic echocardiography showed a large mobile mass in the left atrium. Transesophageal two-and three-dimensional echocardiography showed a large mobile ovoid mass with a narrow stalk attached to the left atrial septum. It was thought to be a myxoma rather than thrombus. Anticoagulation with heparin was continued. When the operation was performed, there was no mass in the left atrium. It must be a thrombus and melt away.

“…Myxoma is characterized by a mobile pedunculated mass originating from fossa ovalis. In some cases in which a thrombus has a stalk, it could be misdiagnosed as myxoma [4]. Typically, this patient was a case of rheumatic MS with a huge LA and thick smoke, together with a large immobile mass which filled the LAA, all in favor of a thrombus.…”

Acquired fistulous communication with the left atrial (LA) chamber has been described in the presence of LA mural thrombus in patients with rheumatic mitral stenosis (MS). Hereby, we present the case of a 74-year-old man with rheumatic MS and a huge LA thrombus found in echocardiography. Coronary angiography revealed an extensive fistula formation feeding mainly from the atrial branches of left circumflex and right coronary arteries and draining into the LA chamber. Moreover, left anterior descending (LAD) and right coronary arteries had slow flow with regional wall motion abnormality in the LAD territory and left ventricular ejection fraction of 35% in echocardiography.

Clot in Lung, Clot in Heart: A Case Report of Tumor-Like Thrombus in Right Atrium

Tumor-like formation of thrombus in the right atrial cavity is rare. It may be mistaken for a myxoma. The exact pathophysiology of an isolated thrombus in the heart is still unclear. Management to prevent complications such as pulmonary thromboembolism depends on the clinical judgment of a cardiologist. This report describes a 76-year-old woman with right atrial thrombus causing subsequent pulmonary thromboembolism in right lung. She initially presented to us with pulmonary embolism, and later, an incidental finding of a mass in her right atrium revealed an association of thrombus in heart with thrombus in lung. The challenging management was to resect this thrombus which was fixed to atrial septum, and a trial of anticoagulation did not resolve it. Exact management of such incidental findings in right heart cavities is not well established. Some cases may benefit from resection of such formed fixed thrombus.
